The basic set of the trimmer consists in a lower load-bearing frame, provided with an universal joint for the tractor, with hydraulic cylinders for adjusting the span, the uplift and the cutting tilt. The cut bar is a movable double blade section, capable of a 80 mm translation. The controls are operated by a control console in the booth, which controls a electric distributor. An holding shaft makes it easier to detach the trimmer once the work has been completed.
